E410/19:

Coinciding disturbing members

The axis of a member falls (approximately) within the circumference of another member.

•if waves have been specified, output data table WAPROF has been produced

(Coinciding disturbing members are not allowed.)

E410/20:

Element 'number' is 'title'

In the WAFOR table, hydrodynamic forces have been defined for the indicated element. However, this element is either WEAK or a JOINT.

Warnings:

W410/1:

Element ground level above water level

For one or more but not all elements holds: W-LEVEL ≤ G-LEVEL.

•all applicable output data tables have been produced

(This can be a normal situation, but also an input error.)

W410/2:

Gravity not between 9.3 and 10.3 m/s**2

In input table PROPENV a unrealistic value has been specified for the acceleration of gravity.

•all applicable output data tables have been produced

W410/3:

Irregular still water surface

The difference between W-LEVEL for an element in open water and the average W-LEVEL exceeds 20 % of the calculated average water depth.

•all applicable output data tables have been produced

(Only elements in open water are considered for the calculation of both the average water and ground level. The average water depth is the difference between the average water and the average ground level. The values of these levels are reported in table VELACC.)

W410/4:

Table OUTDIAM, row 'number' no resulting elem

The pipeline section specified in a row of input table OUTDIAM contains no element.

•all applicable output data tables have been produced

(The table row in question has been ignored.)

W410/5:

Irregular ground surface

The difference between G-LEVEL for an element in open water and the average G-LEVEL exceeds 20 % of the calculated average water depth.

•all applicable output data tables have been produced

(Only elements in open water are considered for the calculation of both the average water and ground level. The average water depth is the difference between the average water and the average ground level. The values of these levels are reported in table VELACC.)

W410/6:

Current profile not ending at g-level

The Z-value in the last row of table CURPROF does not equal the (average) G-LEVEL.

•all applicable output data tables have been produced

(If the last Z-value is above G-LEVEL, the current is kept constant from last Z-value to G-LEVEL, if below G-LEVEL the Z-value at G-Level is determined by linear interpolation.)

(The values from table DEADW increased by the buoyancy have been taken as the weights in air.)

W410/11:

Element(s) in water below mean g-level

There are elements in water but below the calculated mean G-LEVEL.

•all applicable output data tables have been produced

(For the calculation of wave/current forces these pipe elements are considered to be at mean G-LEVEL.)

W410/12:

Probably irregular wave profile

For shallow water and intermediate depth the wave-height/sea-depth ratio is relatively large and Stokes 5 theory has been applied.

•all applicable output data tables have been produced

(Although a solution has been found for the equations describing the Stokes 5 wave theory, the wave profile may contain bumps or even be triple-crested. You should check this by observing the graph of the wave profile in table WAPROF. The resulting velocities and accelerations may be less accurate or wrong.)

M410/1:

Table OUTDIAM, diam row 'number' reduced

For one or more elements of the pipeline section specified in a row of input table OUTDIAM the specified diameter is smaller than the structural diameter from input table DIAM.

•all applicable output data tables have been produced

(It is more likely that the structural diameter should be increased due to possible coatings and marine growth, however reducing the diameter is allowed.)
